Shield tunnel overhead line system anchor bolt hole positioning device and application thereof

Abstract

The invention belongs to application of positioning equipment in subway tunnel construction, and particularly relates to a shield tunnel overhead line system anchor bolt hole positioning device and application thereof. The positioning device comprises a triangular bracket and a laser ranging sensor; the top of the triangular bracket and the lower surface of the base plate adopt a movable ball matching mechanism with a locking device; rotating plates are arranged over a base plate at intervals and assembled with the base plate through shafts in a rotating mode. A first motor on a base plate drives a shaft to rotate through a gear pair, an encoder and a gear pair are assembled in a meshed mode, a second motor is fixed to a rotating plate, a swing rod is fixed to an output shaft of the secondmotor, the laser ranging sensor and a second inclination angle sensor are assembled on the swing rod, and a first inclination angle sensor is arranged on the rotating plate; a control device receivessignals sent by the first inclination angle sensor, the second inclination angle sensor, the encoder and the laser ranging sensor and processes and controls starting, stopping and rotating angles ofthe first motor and the second motor. The method effectively solves a problem that a conventional positioning method is tedious and complex, is accurate in positioning, is simple in device, and is convenient for measurement.

Description

technical field [0001] The invention belongs to the application of positioning equipment in subway tunnel construction, in particular to a shield tunnel catenary anchor bolt hole positioning device and its application. Background technique [0002] The catenary installation and construction of subway tunnels are usually installed after the track is laid. In order to shorten the construction period and change the traditional construction mode, there has been a trackless construction method in which the catenary is installed before the track is laid. It is to simulate the laid track, and then measure and locate; the second is to use the total station to measure, record the data, calculate with the help of other tools, and finally re-position the process. The two methods are cumbersome and complicated.
